Abrégé

AED patient protection circuitry is improved by using triode for alternating current (TRIACs), which are significantly smaller and cheaper than relays. The TRIACs are positioned between a defibrillation waveform generator and the pads through which defibrillation waveforms are delivered to the patient and alternate under the control of a processing element such as a microcontroller between a conductive state in which they allow the defibrillation waveforms to reach the patient through the pads and an isolated state in which they prevent the defibrillation waveforms from reaching the patient through the pads. A voltage monitor interfaced to the microcontroller can monitor current leakage from the TRIACs or other portions of the defibrillator, thus detecting degradation of patient protection circuitry and further increasing defibrillator safety and reliability.
